Thanks! I found something interesting, a function named icalfilter from the ical2html package in Debian/Ubuntu. Very easy to use to filter by categories. Unfortunately, this same package does not exist for openSUSE, but worse case scenario, I can use my Debian server to work on those ICS files.
Depends. Many journals in Evolution/Ecology are still free to publish in non-OA. It’s becoming rarer though because many journals are switching to full (paid!) open access.
You don’t really have to. You could save the workspace along with the history of you commands to load it at a later time, and never have a script at all.
The reason nobody really does that (except maybe if they use R once in every decade) is that it’s not really viable in the middle-term. That is because it doesn’t distinguish between failed attempts and actual, final code and so quickly becomes a mess.
If you don’t have multiple email accounts, then probably a webmail is fine. If you have multiple accounts, and require some advanced email features, then a local client is often more efficient. Unfortunately, because the majority of people are fine with a webmail, those clients are not attracting much activity for development and Thunderbird itself almost died some ten years ago.
